Embodiment Construction

[0065] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0066] In a photovoltaic power generation system, multiple photovoltaic modules are generally installed on the same tracking axis, and different tracking axes are set at a certain distance. When setting the position of the tracking axis, the astronomical algorithm and the inverse tracking algorithm are considered. In theory, the photovoltaic module string on one tracking axis will not block the photovoltaic module string on the other tracking axis. However, in...

Abstract

The invention provides a photovoltaic module tracking control method and a related device, and the method comprises the steps: determining a to-be-adjusted tracking axis and a reference tracking axis in which a photovoltaic module string is not shielded; when the reference power generation performance parameter of the reference tracking shaft and the actual power generation performance parameter corresponding to the tracking shaft to be adjusted meet the preset angle adjustment rule, indicating that the photovoltaic module string on the tracking shaft to be adjusted is shielded, and at the moment, calculating the loss value of the actual power generation performance parameter relative to the reference power generation performance parameter; determining the correction angle corresponding to the loss value and correcting the angle of the to-be-adjusted tracking shaft according to the correction angle, so that the photovoltaic module string arranged on the to-be-adjusted tracking shaft is adjusted to a non-shielded state, the light utilization rate of the photovoltaic module string is improved, and the generating capacity of the photovoltaic module string is improved.

Description

technical field [0001] The present invention relates to the field of photovoltaic power generation, and more specifically, to a photovoltaic module tracking control method and related devices. Background technique [0002] With the continuous development of photovoltaic power generation technology, there are more and more applications of tracking technology for photovoltaic power generation systems. [0003] In a photovoltaic power generation system, multiple photovoltaic modules are generally installed on the same tracking axis, and different tracking axes are set at a certain distance. During the process of the tracking axis tracking the sun, the photovoltaic components on one tracking axis will block the photovoltaic components on the adjacent tracking axis, so that the light utilization rate of the blocked photovoltaic components is low and the power generation is reduced. . Contents of the invention [0004] In view of this, the present invention provides a photovol...
